Elena Suliotis sings some pretty awful notes in her scene. The booing (quite massive - much worse than for girlie man Alagna)
starts around 7:10. Suliotis left the stage and did not want to come back. According to eye witnesses, Callas and Créspin were
in the audience. While Créspin (a soprano with shaky high notes herself) shook her fist and screamed "lâche, lâche",
Callas (a soprano used to get booed) went backstage to console Suliotis. The chaos starts at 8:20 when she does not want to
come back. The entire waiting-for-Suliotis to come back is not uploaded as it lasted about 20 minutes or so. This reminds me
of Scotto getting booed after her aria in Ballo in maschera. She waited for the tenor to come on the scene for the duo, and
then left him not to return at all.
